WILLIAM H. MUZZY, OF DAYTON, OHIO, ASSIGNOR, BY ASSIGNMENTS, TO THE NATIONAL CASH REGISTER COMPANY, OF DAYTON, 0HIO, A CORPORATION OF OHIO,

(INCORPORATED IN 1906.)

ELECTRICAL CASH-REGISTER WITH DISTANT INDICATION.

To all whom it may concern:

Be it known that I, WILLIAM H. MUzzY, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Electrical Cash-Rcgisters-with Distant Indication, of

which I declare the following to be a full, clear, and exact description.

This invention relates to improvements in cash registers and has more particular relation to improvements in indicating devices for the same located at a distance from the machine or. register proper.

The object of the invention is to provide improved mechanism for indicating at a distance, at one or several points, the amounts of the transact-ions which are registered indicated or recorded at the main station where the cash register is located. I A further object is to apply an improved form of distant indication to the type of machine known as a two-motion machine, in which keys are first set and the machine proper subsequently operated by a lever, handle, or its equivalent means.

The invention consists of certain npvel constructions, combinations and arrangements of parts, all of which willbe hereinafter more particularly set forth and claimed. p

In the accom Denying drawings forming part ofthis specification: Figure 1 represents a transverse vertical section througha machine of the type shown in the patent to Clcal and Reinhard, No. 580,378, dated April 18, 1897, with my improvements applied thereto.

Specification of Letters Patent.

Application med December 26, 1903.

. Patented July 4, 1911.

Serial No. 186,741.

for any detail description desired.

In the aforesaid patent but a single indicator wheel is shown while in my present invention each of the groups of indicating devices comprise three indicators, arranged to be actuated by a single motor. The indicators are connected up to the motors through the medium of suitable magnetic clutches and the, indicators are arrested in their movements by the breaking of the circuits through themagnetic clutches whereby the indicators are disconnected from the motor.

In the following specification I will describe the machine as provided with a single group of indicators but it will be understood that as many groups as desired may be provided and made to indicate in difierent rooms or parts of a single roomby' properly connecting the circuit Wires.

The type of machine shown in Fig. 1 is fully described and illustrated in the aforesaid patent to Cleal and Reinhard and it will therefore not be necessary to describe this machine in detail in this application except in so far as the construction of the machine comes into intimate relation with the devices comprising the present invention. The setting keys 1 are arranged in banks as described in the aforesaid patent; each bank containing 9 keys numbered from 1 to 9 and the banks represent units-of-cents, tens-of-cents and units-of-dollars. It will of course be understood that this capacity can readily be increased and the number of indicators correspondingly increased without departing from the spirit of this invention. I have simply selected a three bank machine for the sake of illustration of my improvements. The keys I operate in connection withihe regular registering, indicating and recording devices substantially as shown and described in the aforesaid patent. The shank of each of these keys is provided with a laterally projecting pin 2 which operates through a radial slot 3 formed in a portion be moved with great rapidity but the contacts .47 and 419 will remain together as long as the magnet 51 remains energized even though the notch 46 has been moved under the nose 45 and it is only after the indicators have become fully set and the circuit broken that the lever 43 is allowed to resume its normal position shown in Fig. '1.

By reference to Fig.8 I will trace out the connections for the lefthand indicator which is shown as fully wired to its respective bank of contact pieces on the register. Starting with the battery or source of electrical energy 52 the current passes through the Wire .53 to one of thebinding posts 54 of the motor, thence through-the motor and by wire 55 to the brush 35 of the left-hand indicator; suitable branch wires 56 and 57 passing from the wire 55 to the brushes of the companion indicators. The current passes through the brush 35, to the ring 36, thence through the bobbin of the clutch, to the shaft 21, thence through the arm 24: and magnet 26 to the spring contact piece 25, thence from the successive contact plates 19 to the contact plates 10 by wires 18, thence through all of the plungers 8 which remain undepressed, to the plate 13, thence through the, depressed plunger 8, to the plate 1 2,.

thence by wire 58 through the bobbins 15., 16 and 17, thence by wire 60 to the magnet 51; suitable branch wires 61 and 62 connecting wires 60 to the bobbins 15, 16 and 1'? of the remaining banks of keys; from the magnet 51 by Wire 50 to the contact 19, through contact 47 to lever 4-3. and thence by wire 53 back to the battery thus complct ing the circuit. When the arm 2 L reaches the segment 19, connected to the plate 10 of the plunger 8, which is depressed, the circuit is broken through the magnet 26 and the clutch 34 of that particular indicator with' the result that the clutch ceases to act to force the arm 24, forward and the plunger 27 comes into play to lock the arm 2-1 against further movement. The shaft 31 of the arresting indicator may'continue its movement and in fact does so if the remaining indica tors require a further movement.

In a machine of the type described in this application it is necessary, when a key is operated in one of the amount banks only, to bring the indicators pertaining to the remaining banks to indicate zero, and to accomplish this result I provide each of the banks of keys with a tenth plunger 63 corresponding to the regular plungers 8 except th a plate 14. In this normal position, which is shown in Figs. 1 and 'Z, the plunger 63 is establishing a contact in a manner similar to one of the plungers 8 when the latter is depressed. As this plunger 63 controls the circuit through one of the segments 19 the indi eators would be arrested at zero when the plungers 63 are in this normal position. When any one of the keys in the bank is operated, however, the detent 67 is elevated in a manner well known in the art and the movement of this detent is utilized to force the plungers 63 outward and bring its contact 68 into contact with its contact plate 10. This prevents the indicatorbeiug arrested when its arm 24 reaches the seg ment 19 which is connected to the plate 10,, as the plunger 63 when in this position corresponds to the position of one of the plungers 8 when its respective key is not depressed, Asa rapid operation of the machine might release the regular key detent and thus release the plunger 63 before the operation or the indicator was completed I provide means for holding the plunger 63 in its outward position irrespective of the movement of the key detent 67. This means comprises a pivoted bell crank 69, one end of which bears against the plunger 63. This bell crank is provided with an armature 70. Whenever the plunge 63is -forcedoutward the bell crank 69 is free to pass under a shoulder "4'1 formed on the plunger and does so pass when the plate 1% becomes energized to draw the armature Z 0 downward against it. The bell crank 69 then acts to hold the plunger 63 in its outward position irrespective of the movement of the key detent 6'2.

' it will he seen from the foregoing description that the setting or" the indicators is pre determined by the operation of the keys 1 and the subsequent operation of the machine proper but that independent of this predetermination the indicators are set correctly notwithstanding the keys may have been returned to their normal positions and the machine proper may have finally completed its operation. The controlling parts are only finally returned to their normal positions when the indicators have reached the proper positions to break the circuits. By this means the setting ot the indicators is free from any possibility of fraudulent manipulation attempted by a violent operation of the machine.

Although I have shown series of keys aranged in banks for controlling the respective contact pieces on the machine, it will be understood that T can arrange to have single movable elements which may be moved to different adjusted positions for different amounts in the several banks without departing from the spirit of this invention.

No registering or recording mechanism is shown in thisapplicetion but such mechanism is shown in the patent to. Cleal and r 0 a, .L I

electrically operat c to Reinhard referred to and would in practice be found in any embodiment of this invention.
